j HYDRNT.

Specification of Letters Patent N o.

companying drawings, making a part of this specication, Ain which-` jFigure l, is a vertical section; Fig. tached parts.

The nature of invention consists in fitting 'a tubular valve into thehydrant having two `,series of holes in it, .with a spring to close thelower ones. The lower set communicate with the water pipe, the otherwith the leak; and in connecting therewith a vacuum chamber to receivethe water from the eduction pipe and prevent its freezing up, whichvacuum chamber can also be made( to act and close the induction valve.

The exterior case A, of the hydrant is similar to those. now in commonuse, above the valves;l and is a straight tube; on the lower end ofwhich is a `flange (c) below this is a cylindrical b'oX or chamber B,with a flange around its upper edge by which it is screwed to (a) aplate is let into a recess around the top of chamber B over which andthe flange is a leather ring to pack the joint between the two flangesabove named; the plate (2)) has a hole through its center for a purposehereafter described. From the bottom of chamber B, a tube (b) descendson the outside of which a screw is cut, the bore of this tube is smoothfor a valve to tit and slide up and down in, the lower part being'countersunk to receive the packing on said valve.

The valve, C, is a cylindrical tube made of composition metal, the lowerend of which is solid and has a screw cut on it which receives a nut (c)and has a key (0') passing through it underneath to hold the nut on; arecess is cut in around the upper face of the nut in which a leatherring is put that projects up and fits into the countersink in the end ofthe tube (b). All around the valve there is a row of holes (0) at such aheight above the nut (c) as not quite to reach the top of the tube whenthe packing is up to its place. Near the top of the chamber B when thevalve is shut there is a piston (c3) which is attached to and surroundsthe tube C. This piston lits the chamber in which it works up and downperfectly tight the tube aeao, dated september 1, 1843.

C, just below this piston, has another row of holes similar to those`already described. The tube C continues up to the top of the hydrantwhere it terminates in a spiral inclined plane or segment of a screwthread y C', the upright tube is intersected below this with ahorizontal o-ne `into which` a spout (c4) is screwed on one side, thatprojects through the case and which maybe covered by a shield A', on theother side a plug (c5) is inserted for a purpose hereafter named the.whole of this apparatus can besustalned by a spring (tlf) whennecessary. In the cap of the Acase there is a spindle D, inserted thatprojects above it and has a handle (d) affixed thereto; belowthe cap itis enlarged and its underside is formed like the thread of a screw tofit C, on the upper side next the cap there is a series of frictionrollers (CV), auspindle on `C enters a recess in D for the purpose ofsteadying it. By this construction it is evident that as the handle (d),is revolved the tube C, is forced down by the inclined planes coming incontact, this creates a vacuum in the upper part of the chamber B, andwhen far enough down the holes (0) are below the tube (b)\and afford afree ingress to the water below; when the handle cl is returned to itsplace by the pressure on the under side of piston (c3) which forces upthe tube C; and as soon as the holes (0) are stopped the water from tubeC, rushes into the chamber B thereby freeing the tube and prevent-ingits freezing; l/Vhen the tube is again forced down the piston throws thewater out of this chamber again-where a commonleak is used instead ofthis chamber the spring ((Z) is used to,`

raise the valve and in summer time when the leak is no-t required thespout can be un-` screwed and changed to the other side by turning t-hetube around and stopping off the leak the plug (c5) being also changed.

Another mode of construction which I a slot (c) admits the water througha hole (b) in plate (b) into the tube C which is thence carried up thecase beside the valve rod and connects with a stationary spout.

circular aperture in the center from which a tube (e) projects downwardnearly to the bottom. Into this tube a composition metal ring (e) isfixed having a female screw cut in it, into which the bottom tube of thehydrant can screw. On the bottom of the lowest part of the air chamberare vcast two staples (6) one at each end and at the center there is aninduction tube (c3) to which the supply pipe is attached this issurrounded by a staple (c4) into which the supply pipe (not shown in thedrawing) is put and fastened up against the pipe (c3) by a wedge.

A plank F, is inserted in the ground and the .air chamber E firmly keyedto it by means of the staples (6). Over this a box G 1s fitted downaround the air chamber to the plank; this box extends up nearly to thetop of the ground around outside of the case A, and chamber B. Outsideof this box dirt is filled in and rammed tight. On top of the box aplate of iron I-I ts having projections downward on each side of thebox. In the center of this plate there is a polygonal hole which justiits the outside of the case A and prevents its turning. Ovei* thisearth and the pavement is placed; when the hydrant is to be removed theplace is openedl to this plate which is taken up and the case A can thenbe unscrewed without the trouble or expense of removing the earthentirely from around the hydrant.

What I claim as my invention and desire to secure by Letters Patent isl.The tubular valve C, having two rows of holes in it one above the otherand a packed valve (c) attached to the end constructed and arranged asherein speciiied.

2. In combination with the chamber B and piston (c3) by means of whichthe valve is raised, and which forms a reservoir for the water in thepipe7 when the supply is cut off.

3./I claim the combination ofV the air chambers E with the hydrantconstructed and combined in the manner set fort-h.
